利用Swashbuckle生成Web API Help Pages

利用Swashbuckle生成Web API Help Pages

本文将通过Swagger的.NET Core的实现封装工具Swashbuckle来生成上一篇-《创建ASP.NET Core Web API》的帮助文档。

Swashbuckle简介

Swashbuckle有两个核心组件:

  • Swashbuckle.SwaggerGen: 提供生成描述对象,方法,返回类型等JSON Swagger文档的功能。
  • Swashbuckle.SwaggerUI: 一个Swagger UI工具的嵌入式版本,可以使用上面的文档来创建可定制化的Web API的功能描述,包含内置的公共方法的测试工具。

在middleware中添加并配置Swagger

首先,要将Swashbuckle添加到项目中的project.json

"Swashbuckle": "6.0.0-beta902"

然后在Configure方法中添加SwaggerGen到services集合中,接着在ConfigureServices方法中,允许中间件(middleware)为生成的JSON文档和SwaggerUI提供服务。

执行dotnet run命令,并导航到http://localhost:5000/swagger/v1/swagger.json 查看描述终结点的文档。

该文档用来驱动Swagger UI,可以导航http://localhost:5000/swagger/ui来查看Swagger UI。

UserController里面的每个方法都可以在该页面上通过点击"Try it out!"进行测试。

定制&扩展

API描述信息

ConfigureSwaggerGen方法可以用来添加作者、版权、描述等信息。

services.ConfigureSwaggerGen(options =>
{
    options.SingleApiVersion(new Info
    {
        Version = "v1",
        Title = "User Web API",
        Description = "ASP.NET Core Web API",
        TermsOfService = "None",
        Contact = new Contact { Name = "Charlie Chu", Email = "[email protected]", Url = "http://zhuchenglin.me/" },
        License = new License { Name = "The MIT License", Url = "http://zhuchenglin.me/" }
    });
});

XML注释

通过在project.json添加“xmlDoc”: true来启用XML注释。

ApplicationBasePath获取该应用的根路径,它必须为XML注释设置一个完整的路径,生成的XML注释名称基于你的应用程序的名称。

注意这个界面是通过之前生成的JSON文件来驱动的,所有的这些API描述信息和XML注释都会写入到这个文件中。
